Tnrll/ whom it Hldf/ wmww:

lie it known that I, IRA S. Duwxznn. :1 citizen of the United Stairs, winding at Cleveland, in llw windy of fuyaimgn and 5 State of Ohio, have ill'f llilffl certain mew and nsel'ul lniprmenlvnis in Sheet-Metal Car Ends, of which the following is sgzzeificatmn.

My invention has far {)f its 80 prin'niry objects pmvirlv a wrrugmwl or rihhul sheet metal end SiiiiflLfl in which the vnrrngatium n sl 'engzllnrnmg and sifl Ulllllg' ribs. are so disposed glint the structure will effectually resist all of the various stresses and pressures to which they may be subjected in use; and in which the corrn z w tlons 0'1 ribs, 01 at least: some 0 than are arranged specifically with the purpose 0f enabling the rand strnstnre to take part (if the roof 10nd.

The invention has for a further objacl; such other new and improved construetiens, arrangements and clevines relating to sheet metal 'rzir 07165 as will be described ami claimed.

The inner eln-et 26 is fairmul with a flange 37 \x'l'll'tll l1f 'l:i upon and in suitably Fwrnrnd in ting 0nd sill 38. Pri f rnbly the flange 37 an angular lip 39 whirl: overlaps 1.5m iiinsr fair-B of lhe end sill. H

The sheets 25, 26 are formed with substanliail vertir-al rilm or corrugations 40. 41. l?relerablr earh plate is formed with two snrll ribs which aline with the corresponding ribs onthe other plain. the ribs pref eraiily trrrin-inuting al tin flanges 27, 28 so that ch23 form tugether. in efi'ect, a pair of posts 01 load carrying elements extknriing from substantially the reof (lawn to the floor of the car. In the spaces between the ribs 49, 41 and in the spaces between such ribs and the edges of the sheets areformed transversely extending-ribs .2. With thernrrw gatiuns 0r ribs so disposal on the end the illustrab structure is capable of withstanding all the usual stresses and pressures exerted against the end of a railway car The structure is very stiff and is capable of carrying a part of the load of the roof.

The car end above described may or may not be provided with a door as desired. In the drawings I have shown a door through the lower sheet metal element 26. In order to nullify, so far as possible, the weakening effect of' piercing the sheet with the door opening 43, a flange 44 is struck out from the sheet around the o ening. The door 45 is preferably made 0 sheet metal and is formed on its upper and side margins with the flanges 46, the side flanges having the projecting lips 47 by means which the door is held in place in the -bar guides 48 riveted to the end sheet. The door may be provided with an eyelet 49 which is adapted to be engaged by a hook 530 susendcd on a bracket 51 when the door is raised. The Z-bar guides 48 tend to rigidify the sheet around the door opening. The structure of the door 10 and the outstanding flanges 44 on the sheet serve the same function.

In Fig. 8 I have shown a modified construction. Here the two pairs of vertical ribs of the preceding figures are replaced by a single vertical rib or corrugation 52 on each sheet. At each side of the ribs or corrugations 52 are the oblique ribs 53 and the horizontal ribs 54. In other respects the construction shown in this figure may be the same as that shown in Figs. 1 to 7 inclusive.

While I have described my invention in certain preferred embodiments it will be understood that further modifications might be made without departure from my invention.

I claim:

1. A sheet metal end structure for railway cars formed with strengthening ribs pressed out of the metal and running in a substantially horizontal direction, similarly formed strengthenin ribs non-continuous with said horizonta ribs which extend in substantially vertical direction, with a flange adapted to support the roof of the car, and with an inturned bottom flange which rests upon the end framework of t e car. a V

2. A sheet metal end structure for railway cars formed with strengthening ribs pressed out of the metal and'extending from top to bottom of the end and spaced apart, and similarly formed transverse ribs non-continuous with said vertical ribs and arranged 1n the spaces between the first named ribs and between said first named ribs and the side mar ins of said end.

3. A s cet metal end structure for rail way cars comprising upper and lower sheets formed with flanges at their meeting edges which are secured together, with substantially horizontal strengthening ribs tossed out of the metal, and with substantially vertical ribs similarly formed which terminate at said flanges, the vertical ribs of one sheet being in alinement with those of the other.

4. A our end composed of two sections of sheet metal provided with stiffening ribs or corrugations which aline at the junction of the sections, the said sections having connecting flanges extending from the protuberant sides of the corrugations.

A our end made up of a plurality of joined sections of sheet metal in which are pressed stiffening corrugationsiwhich aline at the junction of the sections, the said sections having connecting flan es extending from theprotuberant sldes ov the corrugations.

6. In a our end, a sheet metal panel rovided with stiffening corrugations and aving an atta hing flange at the ends of said corrugations.

7. In a sheet metal car end, a plurality of sections secured together at their adjacent edges by means of flanges extending at an angle to the car end, corrugations pressed out of said metal and extending across the flanges to stiilcn the end in a direction at an angle to the flanges.

8. in a railway framing, the combination with said fram ing and the longitudinal sustaining inemhers for the roof; of a sheet metal end structure provided at its lowercdge with a horizontally extending flange which stifiens the structure transversely, and at its upper edge with a stiffening flange which serves also to support the longitudinal roof sustaining members, and formed with vertical corrugations which extend substantially from the roof of the car to the'fioor so as to act as beams rigidifying the sheet metal structure vertically.
